THAUMATIN FROM THAUMATOCOCCUS DANIELLII

Thaumatin from Thaumatococcus daniellii has been used:

• as a positive control/standard to detect the amount of recombinant thaumatin in the milk of transgenic mice using western blot
• as a standard to compare its retention time with Vitis vinifera thaumatin-like proteins (VVTL1) occurring in free-run juice and determine the pathogenesis-related protein content in grape juices
• as a model protein to study its interaction with free and ligated decavanadate

Recently it was shown the over expression of the thaumatin gene from Thaumatococcus daniellii in tomatoes caused the fruit to have a sweeter taste, suggesting that thaumatin could be used to enhance the taste of various foods.
